Strokes25Frequency#7458DifficultyVery Hard
Cultural note

In Chinese culture, the concept of time is often viewed with a sense of urgency and the importance of seizing fleeting opportunities, making 一瞬间 a relevant term in both personal and professional contexts.

Memory tip

Imagine a stopwatch that ticks away in just one瞬 (shùn), marking every瞬 (shùn) as a quick flash or moment. The character 一 (yī) means 'one,' so think of it as 'one moment' or 'one instant,' making it easier to remember both pronunciation and meaning.
